Well.... I never completed Braid so I don't know, and don't reveal the twist lol! I got to the last level I think, certainly the last world, and stopped playing. It is a class game though in how it makes you think in different ways to solve the puzzles. The only game I can compare it to (and the comparison isn't immediately obvious) is Portal, another weird platformer that gave me a funny feeling in my head! I'd recommend Braid to the hilt, it can't cost much these days.
